I've just updated ffmpeg to version 0.10.2. The color is the same - dark gray!

Please test current git head. All released versions have more bugs and less features than current git head, only use a release if you are not a user, but if you have to package FFmpeg for other people.

I said I think that this is a regression but I don't know exactly :).
But I know that it is a bug - the color must be black!
I'll try to compile current git head and let you know.

I've downloaded, compiled and linked current git head of ffmpeg.
